[0030] Example 3

[0031] On the basis of Example 2, the circuit structure of the PWM generator 13 is as follows: it includes a NE555 timer, and the NE555 timer includes a VCC terminal, a RESET terminal, an OUT terminal, a CTRL terminal, a TRIG terminal, a DISCH terminal, a GND terminal, and a THR terminal. The VCC terminal is respectively connected to the indicator light 9 and the RESET terminal, the OUT terminal is respectively connected to the resistor R1, the delay loop, and the 185nm ultraviolet LED lamp 14, the end of the delay loop away from the OUT terminal is connected to the 254nm ultraviolet LED lamp 3, the CTRL terminal is connected to one end of the capacitor C3, the other end of the capacitor C3 is grounded, and the TRIG terminal is connected to the 254nm ultraviolet LED lamp 3.

[0032] The circuit working principle of the PWM generator 13 is as follows: after the switch 12 is started, the indicator light 9 lights up, and the PWM generator 13, the temperature controller 5 and the ozone generator 4 are powered at the same time. In the PWM generator 13, the current passes through the resistor R1 and charges the capacitor C1 through the diode D2, and outputs a high level through the OUT terminal. The high level at this time is the initial stage. When the voltage of the capacitor C1 rises from 0V to the THR terminal threshold (the threshold voltage is 2 / 3VCC terminal voltage), the OUT terminal switches to a low level at this time, and the process is a charging process; when the OUT terminal outputs a low level, the DISCH terminal is internally connected to the ground line, so that the capacitor C1 begins to discharge rapidly through the diode D1, and the voltage of the capacitor C1 drops rapidly until the voltage of the capacitor C1 drops to the TRIG terminal threshold voltage ( The threshold voltage of the TRIG terminal is 1 / 3 of the voltage of the VCC terminal), at this time, the OUT terminal switches to a high level again, completing the discharge process of a PWM cycle; to ensure the stability of the NE555 timer, the RESET terminal is directly connected to the VCC terminal to avoid resetting due to unexpected signals, and the DISCH terminal is connected to the ground terminal of the capacitor C1 to ensure that the capacitor C1 is quickly discharged when the OUT terminal outputs a low level to prepare for the next cycle; the CTRL terminal is grounded, and the noise effect is reduced through the capacitor C3 to maintain the stable output of the PWM signal; in addition, the OUT terminal directly drives the 185nm ultraviolet LED lamp 14, and at the same time provides a delayed signal to the 254nm ultraviolet LED lamp 3 through the delay circuit composed of R2 and C2. When the OUT terminal outputs a low level, the capacitor C2 gradually discharges. This charging and discharging process takes time, thereby introducing a delay in the activation of the 254nm ultraviolet LED lamp 3, extending the time it takes for the signal to reach the 254nm ultraviolet LED lamp 3, thereby ensuring that the 185nm ultraviolet LED lamp 14 is activated first, and then the 254nm ultraviolet LED lamp 3 is activated, thereby achieving the use of the 185nm ultraviolet LED lamp 14 for disinfection and sterilization first, and then using the 254nm ultraviolet LED lamp 3 to decompose ozone.

[0033] The working process of the embedded antibacterial disinfection coil pad of the utility model is as follows: the second antibacterial fabric 15 is covered on or wrapped on the article to be disinfected, the switch 12 is turned on, the indicator light 9 is turned on, and after the parameters of the PWM generator 13 and the temperature controller 5 are set, the 185nm ultraviolet LED lamp 14 is triggered to generate ultraviolet rays in the 185nm band, the graphene heating plate 2 is triggered to heat to about 40°C, and the ozone generator 4 is triggered to generate ozone. At this time, the article to be disinfected is sterilized and disinfected by ultraviolet rays and ozone in the 185nm band. After the set sterilization and disinfection time is reached, the 254nm ultraviolet LED lamp 3 is triggered to generate ultraviolet rays in the 254nm band to decompose ozone to prevent ozone from causing harm to the human body, the second antibacterial fabric 15 is opened, and the article to be disinfected is taken out.

[0034] The utility model has an embedded antibacterial disinfection coil mat, the disinfection time can be set independently, it is safe, no harmful substances are emitted, the power consumption is low, and it is thin and light and foldable.
